Why not wear a varsity jacket with a white short sleeve shirt? Both of these pieces are super comfortable and look nice teamed together. When not sure about the footwear, complement your getup with a pair of white and black leather low top sneakers. This one is a viable choice when it comes to crafting a well-coordinated outfit for unpredictable fall weather. Ideal to portray that even as a gentleman in his 20s you're confident enough to own your style choices.
